Description
When you’re dealing with an older tractor that’s been giving you starting troubles, especially on those cold mornings, a worn-out ignition switch can leave you stranded right when there’s work to do. This dynamo-type ignition switch with heat start capability is designed for the older Massey Ferguson and Case IHC models that have stood the test of time but need reliable electrical components to keep them running strong.
What You’re Getting
- 14mm mounting diameter fits the original dash opening without modifications
- Heat start circuit helps warm diesel engines on cold mornings for easier starting
- Dynamo-type design works perfectly with generator-equipped older tractors
- Direct replacement that connects to your existing wiring harness
- Durable construction handles the vibration and temperature swings of daily farm use
Built for Classic Farm Workhorses
This switch is designed for those dependable Massey Ferguson tractors from the 35, 65, 100, and 700 series, along with Case IHC B-series models that are still earning their keep on farms and small operations. These are the tractors you rely on for hay work, brush cutting, loader tasks, and general farm chores where dependability matters more than fancy electronics.
Made to Last
The switch housing and internal contacts are built to handle the electrical loads of dynamo charging systems and the heavy-duty starting circuits these older tractors require. The heat start feature is especially valuable for diesel engines that need a little extra help firing up when temperatures drop.
Installation Notes
The 14mm thread size matches the original dash mounting, so installation is straightforward—just disconnect the battery, remove the old switch, and thread in the new one. Make sure to connect the heat start wire properly if your tractor uses this feature for cold weather starting.
